Thank you all, guys. Thanks for your advices and encouragement. The situation is crazy and all we can do is try our best to save ourselves.
Yes you're right, if I want to get money during this quarantine, I can do online freelance jobs and learn about crypto at the same time. It's hard for a newbie to get income from trading, so I'll try some bounties and airdrops first. I've been searching the basic info about crypto currency last week. I'll try anyway.
